FEATURES

The good flexibility and the high pressure capability of the type SP.T.9750, together with
its good capacity to absorb vibrations, offer the user an economical and long-lasting
solution to overcome those problems deriving from a dynamic offset or from cyclic motion.

FITTINGS

Of any type in carbon steel, malleable cast iron, brass, bronze, stainless steel, or
combination of stainless steel and carbon steel. Attachments can be made by electro-
welding (type EL), brazing (type BA and Bf), reusable fittings, etc.

USE

Wherever very severe ambient conditions are combined with chemical aggressively, high
temperature pressure or vacuum, frequent movement, static or dynamic offset, vibration,
permeability (rare gasses), etc.

MILL LENGTHS

depending on diameters. Indefinite lengths (obtained by argon-arc-Welding) can be supplied on application.
